Are smart hose timers reliable enough to leave running while on vacation?

Mixed picture. Verified-purchase reviewers and high-trust subreddit threads on r/lawncare and r/homeassistant report multi-season reliability from LinkTap and (mostly) Rachio. Orbit B-hyve draws the loudest complaints on r/Irrigation about app stability, firmware updates, and units leaking or failing after about a year, though a high-trust r/smarthome thread notes the valves themselves open and close well. Battery monitoring and a backup plan for hub disconnects are wise either way.
